Patented July 24, 1934 UNITED STATES PATENT. OFFICE The presentinvention relates generally to improvements in typewriting machines andthe primary object of the invention is to provide means whereby astandard typewriter may be converted into a machine of the combinationback and front feed type for check writing, invoice making and similaruses.

A further object of the invention is to provide a check writing devicefor typewriters wherein writing, registering and protecting of the checkmay be simultaneously accomplished in one typing operation.

A further object of the invention is to provide a typewriting machine ofa construction to receive a record or register sheet provided withduplicate columns of identification numbers for display at sightopenings arranged adjacent opposite ends of the platen for the purposeof correctly aligning the sheet relative to the printing line and alsoindicating the numbered position of the sheet; together with meanswhereby a numbered check or similar sheet, so designed as to have allnecessary information typed on'a single line, may be inserted at thefront of the platen into correct writing position and in directcollation with the register sheet so that in the act of typing upon thecheck a record is also made upon the register sheet on a line betweenthe identification numbers corresponding to the number of the check.

A further object of the invention is to provide improved means wherebythe check may be easily guided into proper position at the front of theplaten and effectively held in position by means automatically moved outof holding relation to the check during the line spacing operation.

A further object resides in the improved construction of the paperholder which in addition to holding the paper in proper typing positionat the front of the platen serves as an aligning means for the registersheet and as means for disposing the check in proper relation to thesheet.

A further object resides in the arrangement whereby the pivoted paperbail is automatically swung to an inoperative position thru actuation ofthe line spacing and carriage return lever.

A still further object of the invention is to provide a check writingattachment for typewriting machines which is of simple construction andmay be applied to typewriting machines of standard construction withoutalterations thereto prohibiting ordinary use of the machine.

Referring to the drawings in detail, and wherein similar referencecharacters designate corresponding parts thruout the several views, theletter A designates a standard form of typewrit- 5 ing machine such asshown by way of example 9 in mechanical make-up in Patent Numbers1,105,657; 1,427,464; 1,635,408; and 1,785,445. altho it is to beunderstood that the check writing attachment may be equally well appliedto various other types of typewriting machines for converting thestandard form of machine in a combined check writing, protecting, andregistering machine. The typewriting machine A includes the usual mainframe B having mounted thereon the usual carriage C having slidingmovement from side to side of the frame B.

The main frame B has mounted therein the usual bank of keys 5 foroperating the type bars 6. The carriage C is mounted for transversemovement at the rear upper portion of the frame B as upon a stationaryrail or race way '7. Arranged on the upper part of the frame Bimmediately forward of the carriage C are the usual top or cover plates8 and 8' having flat upper surfaces at their rear portions which are inparallel aligning relation to the direction of travel of the carriage C.Arranged between the rear edge portions of the top plates 8 and 8 is theusual type bar guide 9. Arranged centrally of the top plate and suitablyfixed to the main frame with its upper edge at the printing line anddisposed symmetrically on both sides of the print-- ing poin is theusual number gauge or scale plate 10 having the end portions thereofturned outwardly or forwardly as at 11. The rear face or surface of thisgauge or scale plate 10 is disposed just forwardly of the rear edge ofthe top plates 8 and 8' so that a sheet inserted behind the scale platemay have its lower edge rest upon the upper surface of the top plate.

The carriage C comprises a frame including a traveling or base rail 12supported for movement upon the stationery rail 7 by the bearings 13 andcarried by the ends of the base rail 12 are the usual end plates 14 and14 in the forward portions of which ,is mounted the platen 15 as upon ashaft 16 journaled in the end plates. Extended about the lower portionof the platen 15 is the usual paper pan or apron 17 for guiding thepaper inserted at the rear of the platen under and upwardly at the frontof the platen just rearwardly of the scale plate 10. Projecting upwardlyand rearwardly at an angle from the paper pan 17 is the usual papertable 18. In the example shown the paper table 18 is of that typedisclosed in Patent 1,458,269 and provided adjacent its left hand endwith a paper gauge 19 against which the left marginal edge of the paperengages.

Normally urged toward the platen 15 at the lower side thereof are thefront and rear pressure or feed rolls 20 and 21 respectively.

Formed on the end plate 14 is an extension 22 for pivotal mounting of acarriage return lever 23 in the form of a bell crank lever pivoted at24. The usual line spacing means 25 is provided at the end of the platen15 and operatively connected by a link 26 to the lever arm 27 of thecarriage return lever 23. The carriage return lever 23 is of the wellknown spring returned type so connected with the line spacing means 25as to cause rotation of the platen 15 when the lever 23 is engaged forreturning the carriage C to its starting position toward the right handend of the typewriting machine.

The swinging bail of the type shown in Patent 1,785,445 is provided forholding the paper against the platen and movable away from the platen topermit of placing of paper above the platen. This paper bail includesthe usual graduated rod 28 extending parallel with the platen 15 andmounted at its ends in the swinging bail arms 29 and 30 pivotallymounted as by pivots 31 to the end plates 14 and 14' rearwardly of theplaten 15. The rod 28 has mounted thereon the usual rolls 32 which whenthe bail is in a lowered position overlie the platen 15. In the normalconstruction of the machine, each of the bail arms 29 and 30 is providedadjacent its pivot 31 with 2. lug 32' to which is attached one end of acoil spring 33 having their opposite ends pivotally connected to thecarriage end plate. In the standard construction, the coil springsconnected to the swinging bail arms act to yieldably urge the rolls 32toward the platen 15 and are so connected with respect to the pivot ofthe arms as to hold the bail in a raised position as in Figure 1 of thedrawings. In converting this form of standard typewriting machine into acheck writing machine as disclosed in this invention, it is preferredtho not entirely essential that the bail arm spring 33 for the bail arm30 be dispensed with to permit for ready and easy applying of myattachment.

The construction and operation of the typewritins' machine A as thus fardescribed is well known in standard forms of typewriting machines andforms no part of the present invention. The invention as hereindisclosed provides means whereby typewriting machines of standardconstruction may be readily and easily converted into a check writingmachine whereby duplicate copies of checks may be recorded in an orderlymanner upon the register sheets.

recording to this invention there is provided mechanism whereby atypewriting machine of standard construction may be converted into amachine of the combination back and front feed type for the writing andrecording of checks in a single typing operation and thereby resultingin a material saving of time over prior methods used. Hingedly carriedby the carriage C is a paper guide and holder 40 embodying a pair ofattaching plates 41 which are secured to the front face of the lugs 42,provided on the carriage base rail 12 at points adjacent opposite endsthereof, as by suitable fastening screws 43. These lugs 42 as shown inPatent #1,105,657 normally serve as mountings for a gauge and scaleadapted to coact with the end portions of the platen. Hinged at itslower edge to one of the attaching plates 41 isa right hand gauge plate44, while hinged at its lower edge to the other attaching plate is aleft hand gauge plate 45. The hinge joints 46 of the gauge plates are inaxial alignment and extend parallel with the platen 15 in a relationthereto forwardly of and below the axis of the platen shaft 16.

These gauge plates 45 and 46 have their u per portions extended abovethe line of print 0 the platen and are normally urged against theopposite end portions of the platen 15 by suitable coil springs 47connected between the gauges and the rear portion of the base rail 12.These plates 44 and 45 are formed with forwardly curved portionsconforming to the contour of the platen 15 and provided in the curvedportion of each plate is a sight opening or window 48 as clearly shownin Figure 4. These sight openings 48 are so disposed as to align withthe printing line of the machine beyond the ends or margins of theprinting line.

Connecting the gauge plates 44 and 45 above the sight openings 48 is apaper holding rod 49 which extends parallel with the platen and engagesthe platen at a location slightly forward of the bail rolls 32 as shownin Figure 5. This rod 49 serves to hold the register sheets 50 andcarbon sheet 51 in a rearwardly directed position over the platen 15when the paper bail is in a raised position as shown in Figure 1. Itwill also be noted that the paper holding rod 49 also serves to connectthe gauge plates 44 and 45 for unitary swinging movement toward and awayfrom the platen.

Mounted upon the upper side of the top plate 8' adjacent the rear edgethereof is an angle or L-shaped guide plate 52 having its upturnedflange 53 extending parallel with the platen 15 and spaced slightlyforward from the rearward edge of the top plate 8' as shown in Figure 5.The upturned guide flange 53 has its upper edge curved forwardly and hasits inner end extended for a short distance behind the angular righthand end 11 of the center gauge plate 10. The rear surface of the guideflange 53 is in alignment with the rear surface of the center gaugeplate 10. Mounted upon the upper surface of the top plate 8 is an angleor L-shaped guide plate 54 having its upturned flange 55 in directalignment with the rear surfaces of the guide flange 53 and center gaugeplate 10. These stationary guides 52 and 54 may be secured to theirrespective top plates ward of the front pressure rolls 20 and a narrowspace is provided for insertion of a sheet such as a check 58 into aprinting position at the front of the platen 15.

The left hand gauge plate 45 extends for a short distance above theholding rod 49 and has formed at its inner edge above the sight opening48, a forwardly extending stop flange 60 extending at a right angle tothe platen 15. This stop flange 60 serves to limit sliding movement ofthe check 58 toward the left side of the machine and properly positionsthe check with respect to the register sheet 50. The upwardly projectingportion of the gauge plate 45 also provides a hand hold whereby theguide and holder 40 may be swung away from the platen for placing of thesheet 50 and carbon 51. In order to permit placing of the check 58 in awriting position, means is provided whereby upon return of the carriageC by the combined carriage return and line spacing lever 23, the paperbail comprising the rod 28 and guide arms 29 and 30 will be swung to araised position away from the platen 15. This bail raising meanscomprises a coupling rod or link 62 connected at its forward end as by auniversal coupling joint 63 to the short lever arm 27 of the carriagereturn lever 23. The rear end of the rod 62 is bifurcated as shown indetail in Figure 7 to provide a terminally opening slot 64 whichreceives the cylindrical spring attaching lug 32' of the swinging bailarm 30. A small retaining bolt 65 is placed in the slot 64 at the rear'of the lug 32' and provides means for attaching the guide arm 30 to therear end of the rod 62 whereby upon movement of the return lever 23 forreturning the carriage C to a starting position, the paper bail will beraised to an inoperative position as shown in Figure 1. The rod 62 maybe held against movement axially off of the lug 32 thru its fitting inthe usual annular groove provided for receiving one end of a coil springas at 33 serving to yieldably retain the paper bail in either a raisedor lowered position. As before stated, it is preferred that the usualbail swinging spring be removed from the lug 32 of the bail arm 30 topermit attachment of the coupling link or rod 62.

Carried by the graduated rod 28 of the paper bail is a tucking device 66including a spring frame 67 slidably and non-rotatably mounted upon therod in straddled relation over the right most of the rolls 32. Mountedin the free end of the frame 67 on an axis parallel with the rod 28 is asmall tucking roll 68 which is engageable with the platen 15 below thepaper holding rod 49 when the paper bail is in its lowered operativeposition as clearly shown in Figure 5. This manner of gripping the checkat its right hand edge insures movement of the check with the platenduring the typing operation. The frame 67 is preferably formed of aspring material to insure contact of both the rolls 32 and the tuckingroll 68 with the paper both above and below the rod 49.

The front pressure rolls 20 have their right hand ends beveled as shownin Figures 1 and 3 and this is to prevent catching of the left hand edgeof the check upon the rolls when the check is being inserted.

Referring particularly to Figure 8, the checks for use with the machineare preferably designed so that all necessary information is typed in asingle line from left to right under suitable headings divided byvertical lines. Figure 8 shows a partially completed check illustratingthe single line of typing. In the first column at the left of the check,the usual check number as at appears, the check having been previouslynumbered as in usual practice. 1

With reference to Figure 9, showing a fragmentary portion of thepreferred form of register sheet 50, the sheet is designed to have theexact left to right spacing and vertical ruling as that of the check foruse with the sheet. The register sheets 50 are designed for registeringone hundred checks and are provided adjacent each vertical edge withlike columns of figures 81. These figures are vertically spaced equal tothe line spacing of the typewriting machine and run from 01 to 00 onboth the right and left margins of the sheet. These columns of figures81 are spaced transversely of the sheet equal to the distance betweenthe sight openings 48 of the paper guide and holder 40 whereby thenumbers of each column will be readable at both sight openings forcorrectly aligning the register sheet and indicating the numberedposition of the sheet.

In use of the machine, with the paper bail in a raised position, theregister sheet 50 and carbon 51 are inserted at the back of the platen15 and rolled under and up around the front of the platen in the usualmanner of placing a letter sheet in an ordinary typewriter. The holder40 may need to be swung away from the platen to permit ready passage ofthe inserted edging of the sheet and carbon beneath the rod 49 and thismay be accomplished by grasping the upper end of the gauge plate 45. Theleft edge of the register sheet is moved into engagement with the papergauge 19 of the paper table 18 in the usual manner of aligning thesheets and when in this position the columns of numbers 81 will alignfor movement past the sight openings 48. The platen is then rotated forbringing the first numbers 01 of each column to register at the sightopenings 48 as shown in Figures 1 and 4. When like numbers appear ateach of the sight openings, the register sheet is properly aligned andthe numbered position-of the sheet is indicated at the sight openings.The carriage C is then moved to a position adjacent its right hand limitof travel and the machine is now in condition for insertion and writingof checks bearing the number 101. The register sheets 50 are allnumbered alike, and in the example illustrated, the numeral 1 as shownat in Figure 9 and designating the current serial number of checks isinserted in pen or pencil before 01 of the left hand column of figuresto indicate that the register sheet is conditioned for registering checknumbers from 101 to 200.

The machine is now in condition for writing check numbers 101 and itwill be noted from Figure 4 that the last two numbers on the check maybe checked with the numbers occurring at both of the sight openings 48to determine if the register sheet is in the correct position forwriting the numbered check. The check bearing number 101 is theninserted at the front of the platen 15 and behind the guide plate flange53 with the left or numbered end of the check approximately aligningwith the left hand end of the guide flange. The check is guideddownwardly between theflange 53 and front pressure rolls 20 until itslower edge rests upon the upper surface of the top plate 8' of themachine frame and after which the check is fed toward the left of themachine behind the center scale plate 10 and guide plate flange 55 untilthe left hand edge of the check abuts the stop flange of the gauge plate45. The top plates 8 and 8' of the machine frame thus form guides forthe lower edge of the check whereby the space on the check for fillingin aligns with the printing line of the platen. The top of the check isthen bent rearwardly over the platen and the paper bail is pulled downinto position as shown inFigure 5- whereupon the tucking device 66engages the right hand edge of the check and firmly holds the check inplace. The check is now in the correct writing position and in properrelation to the register sheet whereby data typed in a single line onthe check will be recorded on the register sheet in alignment betweenthe check registering numbers 01.

After writing of the check, the operator grasps the forwardly projectinglever arm of the carriage return lever 23 and returns the carriagetoward the right for its limit of movement to a starting position. Thispull on the carriage return lever 23 turns the platen for one line spaceby its connection with the line spacing means 25 and moves the registersheet 50 and carbon 51 up one line space into a position for recoringthe next check which will be numbered 102. Movement of the lever 23 alsoimparts rearward movement to the rod 62 which swings the paper bail arms29 and 30 upwardly and the rod 28 carrying the rolls 32 and tuckingdevice 66 to an elevated inoperative position as in Figure 1 so as topermit ready and easy removal of the check from the front of the platen.The check registering numbers 02 will now be visible at the sightopenings 48 and the machine in a position for insertion and writing ofcheck numbered 102. Thus the successively numbered checks may be writtenand recorded on the register sheets between identification numbers foreach check written.

The usual numbers on the type bars 6 are changed to the pin point typein order to obtain perforated numbers serving to protect the checkagainst attempts at forgery or alterations.

Thus it will be seen that the invention discloses means whereby thestandard typewriting machine may be-easily converted into a checkwriting machine of the combination back and front feed type. A novelarrangement has also been disclosed whereby writing, registering andprotecting of checks may be simultaneously accomplished in one typingoperation.

Changes in detail may be made in the shape, size and arrangement ofparts as herein shown and described, as well as application of thedevice to other forms of typewriting machines than that shown described,without departing from the spirit of the invention or the scope of thefollowing claims.
